I'm not a professional, I shoot for myself and I don't know many terms like "overrunning through infinity" or aberrations, so I'll make it short and clear. This lens, with a little skill, will allow you to shoot "like a photographer", i. E. with a really blurry background and good detail and brightness. And where your whale lens gave out dark porridge - this one can still take a decent photo. Considering its price, it's just a non-alternative option, thanks to the Chinese. Attached are examples of unedited photos.
